Regular ol' 4Matic. I have std. 18x8.5 factory wheels. I found a set of chrome Divino's @ 18", but are 7.5" and +35*. They aren't high end, but I know they'll fit the wheel well. I just put a new set of Extreme Contact DWS on. They are the size prescribed for the car. Question is will these Conti's fit a wheel only 7.5" wide? The Divino's have new lug bolts, hub space etc., but the big unknown to me is will the tires transfer okay. Thanks.
